Biogas recovery from a temperate climate covered anaerobic pond
New Zealand has over 1000 anaerobic waste stabilisation ponds treating wastewater from farms and industry. Traditional anaerobic ponds were not designed to optimise anaerobic digestion to produce biogas and are therefore uncovered, releasing biogas to the atmosphere, which can cause odour problems and contributes to GHG emissions. The biogas production and treatment performance of an anaerobic ...

Nutrient recycling and management of press mud, parthenium and biogas plant slurry employing earthworms
Sugar industry has been included in the list of the most polluting industries. The aim of this study was to transform sugar mill sludge (PM) and Parthenium amended with Biogas Plant Slurry (BPS) into vermicompost employing Eisenia fetida. In all the waste mixtures, a decrease in pH, TOC, TK and C : N ratio, but increase in TKN and TP was recorded. Maximum worm biomass and growth rate was attained ...

Potential biogas production from sludges and msw in Uruguay
Sewage treatment Montevideo's sewage is disposed into the sea by means of an outfall. Nevertheless as there are a lot of cities that are not on seashore, and most of these cities are discharging their effluents into rivers without proper treatment, a more strict sewage treatment must be done in order to achieve the discharge standards. For the 1,780,000 inhabitants the current sewage coverage is ...

DC WASA adopts thermal hydrolysis for anaerobic digestion pretreatment: conceptual design details for the largest Cambi™
ABSTRACT The District of Columbia Water and Sewer Authority (DC WASA) has decided to incorporate thermal-hydrolysis pretreatment in conjunction with mesophillic anaerobic digestion as the backbone of a long-term biosolids treatment plan to produce Class A biosolids. The Authority has been lime stabilizing their raw solids from the Blue Plains Plant for many years, transporting them to the State ...

Recovering energy from biogas emission: the case of Mariana Mantovana landfill (Italy)
This paper deals with the analytic rating of the economic investment in an energy recovery plant for municipal waste, in relation to the estimate of its capability to exploit biogas production transformation, and sale of electricity production, and the Green Certificates. The approach entails the assessment of potential scenarios of biogas flare coming from its production forecasts, according to ...

Role of primary sedimentation on plant-wide energy recovery and carbon footprint
The goal of this paper is to show the effect of primary sedimentation on the chemical oxygen demand (COD) and solids fractionation and consequently on the carbonaceous and energy footprints of wastewater treatment processes. Using a simple rational procedure for COD and solids fraction quantification, we quantify the effects of varying fractions on CO2 and CO2-equivalent mass flows, process ...

Project - Biogas Desulfurization at ETAR do Norte (Portugal)
The Wastewater Treatment Plant (ETAR) do Norte is one of the largest in the central region of Portugal, serving several municipalities. The infrastructure is located in the area of Coimbra, Leiria, occupying 6 hectares of land; it receives effluents from about 250,000 inhabitants of several municipalities. It has the capacity to treat some 38,000 m3 of wastewater daily, of which 77% is domestic, ...

Project - Biogas purification at Mapocho WWTP
Biogas is a mixture of gases, the main components of which are methane and carbon dioxide, produced as a result of the fermentation of organic matter in the absence of air by the action of a microbial consortium (anaerobic digestion). The composition of the biogas depends entirely on the nature of the waste used and the conditions under which anaerobic digestion is carried out. Generally, the ...

The Benefits of Biogas Conditioning
Abstract Anaerobic digestion is quickly becoming the choice technology for sewage sludge treatment at wastewater treatment plants, as the methane rich biogas produced is a valuable resource which can be used to generate electricity. In the oxygen restricted environment, a natural by-product of the anaerobic process is hydrogen sulfide, a harmful contaminant. Also present in the biogas are ...

High solids anaerobic digestion of pfmsw using novel anaerobic reactors
In the last decade efforts have been made to control anaerobic digestion of the putrescible fraction of municipal solid waste (PFMSW) in engineered reactors, than to allow for 'free' digestion in landfill sites. Such a process achieves enhanced treatment efficiency in significantly reduced retention times (from years down to days) and completes energy recovery from waste, without biogas emissions ...

Increasing methane content in biogas and simultaneous value added product recovery using microbial electrosynthesis
Electrosynthesis of multi-carbon compounds from the carbon dioxide present in biogas is a nascent approach towards purification of biogas. Microbial electrosynthesis (MES) cells, fabricated using different electrode materials, were operated using different electrolytes and mixed anaerobic culture as biocatalysts in the cathodic chamber under an applied cathode potential of −0.7 V vs standard ...

Siloxane Removal
SILOXANS IN BIOGAS. ORIGIN, EFFECTS AND TREATMENTS Biogas from landfills, digestion and wastewater treatment plants (wwtp) is a valuable material for the production of energy, biofuels and the production of chemical products such as hydrogen and methanol. As it is a source of renewable energy, it is inexhaustible, clean and can be used as planned. Their use generates less environmental ...

Turning waste into power
Economic, social and environmental factors dictate the necessity to manage waste to a new level. Wastewater plants, landfills, farms and food plants are all the owners of biomass that can be digested to produce biogas and turned into power. Biogas can be burned directly in boilers for heat recovery and used for manufacturing, heating or cooling; this is the simplest method of direct biogas ...
